Configurations of the KINARM robot used to apply forces to the upper and lower arm segments via arm troughs (arm configuration shown to the left) or to the hand via a handle (hand configuration shown to the right). In the hand configuration, the elbow was supported by a cushioned air puck, and subjects grasped a handle. The upper and lower arm segments did not otherwise contact the apparatus.

Mean hand-path area results for experiment 1, in which the imposed force fields depended on the velocity of the hand. The field was applied either to the hand via a handle (subscript h) or to the arm segments via an exoskeleton (subscript a). Data are shown for sessions 1 and 3 (first and second A). A block is a set of reaches to all eight targets. Each dot represents an average across subjects, and the vertical lines represent 1 SE. Exponential curves are fitted to each session of each group. The elevated dots at the right of each panel represent the average of two catch trials delivered in blocks 29 and 30.

Joint-path area results for experiment 2, in which the imposed force fields depended on the angular velocities of the joints. Labels are as in Figure 2. deg, Degree.
